class PolynomialXY : public Polynomial
  /*!
  This class implements a polynomial with two variables X and Y.
  DESCRIPTION :
  The coefficients a_i of a polynomial are stored in the following sequence:
  2                2       3
  p(X,Y) = a1 + a2 X + a3 Y + a4 X  + a5 X Y + a6 Y  + a7 X  + ...
  REMARK :
  The degree of such polynomial is temporarily limited to 1 ; it can be
  easily increased whenever required.
